ARTHUR A. BRIGHAM, OF IVESTON, MASSACHUSETTS.

WINDING-MACHINE.

SPECIFICATION forming part of Letters Patent No. 503,277, dated August 15, 1893.

Application filed March '7, 1892. Serial No. $24,081. (No model.)

To all whom it may concern.-

Be it known that I, ARTHUR A. BRIGHAM, a citizen of the United States, residing at \Veston, in the county of Middlesex and State of Massachusetts, have invented certain new and useful Improvements in inding-Machines, of which the following is a specification, reference being had to the accompanying drawings.

My invention relates to the spindle-holder, or bracket, for a winding machine, of that class in which the spindle and load thereon is held against a drum which, revolving, causes the spindle and load thereon to revolve, owing to the friction of their contact with the drum.

The object of the invention is, to so construct the holder or bracket, for the spindle, that it may be readily adapted to hold in suitable position with reference to the drum a cylindrical or a conical spindle, and that the holder may operate in other respects more satisfactorily than heretofore.

My invention consists in the devices and combinations of devices hereinafter set forth and specifically pointed out in the claims.

In the drawings, two sheets, Figure 1 is a sideview and Fig. 3 a plan of a spindle holder or bracket, embodying my invention. Fig. 2 is a section taken in the direction of lines 1 1 in Fig. 8. Figs. 4 and 5 are front views illustrating the adaptation of the device for different forms of spindles.

The holder A has two places CL a of bearing on a rod or shaft 13 which in the winding machine supports one or more holders or brackets. The holder or bracket has two arms I) and 0 between which the spindle is to be placed, the outer ends of these arms having bearings for the journals of the spindle. The arm I) has a vertical slot (1 formed in such a manner that the journal of the spindle may bear at the upper end 6 if the spindle lies on the driving drum, or bear at the lower end f if the spindle is held up by the holder or bracket. From the slot d extends outward a slot 9 for the convenient insertion or removal of the spindle. The arm a has a slot h in which a block 1' is fitted to slide vertically. A screw j is formed to revolve in the arm at 7.:

and to screw into the block 2' as at Z. This block has an opening or bearing on for a journal of the spindle. Now, by suitably raising the blockz' by means of the screw, the bearing therein may be placed in the position required for a cylindrical spindle as illustrated in Fig. 4, or for a conical spindle as shown in Fig. 5. It is not always necessary that a cylindrical spindle should bear against and be driven by a cylindrical drum, or a conical spindle bear against and be driven by aconical drum, but with certain qualities of yarn a spindle of either form may be driven by a cylindrical or a conical drum.

My adjustable holder or bracket is very useful, since the same holder or bracket may be employed for either style of spindle, and is particularly desirable when no change of driving drum is required.

In order that the spindle may be supported steadily and the required pressure on the drum be maintained, a spring 0 is secured to the holder or bracket in such a manner as to press on the rod or shaft B. This spring is secured to the holder or bracket and adjusted to get the required pressure on the rod or shaft, by means of a screw it which screws into the cross piece 0 of the holder, at p. I place a not Q on this screw, which nut being screwed firmly against the cr0ss-piece of the holder or bracket, will prevent the screw from becoming loose so as to vary the required pressure of the spring against the rod or shaft, and the desired pressure of the spindle and its load on the driving drum.

I claim as my invention--- 1. A spindle-holder, or bracket, for a winding machine, having two arms to support the spindle, one of said arms being provided with a movable block to receive a journal of the spindle, and a screw to move said block, substantially as and for the purpose set forth.

2. A spindle-holder, or bracket, for a wind ing machine, having two arms, one of which is provided with a slot to receive one journal of the spindle, the other arm being provided with a block to receive the other journal of the spindle, and a screw to move said block and to secure the same in position, substantially as and for the purpose set forth.

3. In aspindle-holder,orbracket,f0r awinddle at one of said arms, and a screw for moving machine, provided with bearings for a ing said block, substantially as described. rod or shaft, and a spring adjustably secured to the holder or bracket to press on said rod 7 ARTHUR BRIGHAM 5 or shaft, the combination with two arms for WVitnessesr supporting the spindle, of a movable block W.
